In this question, it is given that, A rectangle with a short side of 6. An arrow points to a smaller rectangle with a short side of 1.5 .
The shorter side of first rectangle is of measurement 6 units and of second rectangle, is of size 1.5units .
To find the scale factor, we have to do division of the shorter sides of the first and second rectangle, that is
So the scale factor is 0.25 .
The correct should 356 yards^2
to solve this you simply add the are of the two squares after you calculate the area for each of them.
